Question

Julie collects antiques. She bought one antique for $300. Its current value is represented by the expression 300(0.75)t, where t is the number of years Julie has owned the antique. Is Julie’s antique going up or down in value?

Answer 1

The vaulue is decreasing since you multiple by a decimal which isn’t a whole number.

Answer 2

The value in this case would be going up. Since .75 being multiplied by an increasing number would only increase, the value must be doing the same.

However, if that t were an exponent, the value would be decreasing. The more a number between 0 and 1 is multiplied by itself, the smaller it gets.
